Chemical Structure
Description
Based on its molecular formula C10H13NO4S, Glipizide Impurity 43 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 243.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Glipizide Impurity 43 (CAS CATO-C4X-140743) is a certified pharmaceutical impurity reference standard with the molecular formula C10H13NO4S and a molecular weight of 243.28 g/mol.
